PEEFACE. 



The twentieth volume of the British Ornithologists' Club 

 contains the report o£ our Migration Committee on the 

 movements in England and Wales of a number of common 

 migratory species during the spring and early summer of 

 1906. 



Mr. H. F. Witherby having tendered his resignation and 

 Mr. M. J. Nicoll having accepted an appointment in the 

 Ghizeh Zoological Gardens in Cairo, it became necessary to 

 appoint two new members, and Messrs. C. B. Rickett and 

 C. B. Ticehurst were elected to fill the vacancies on the 

 Sub-Committee. 



The Members of our Migration Committee are jointly 

 responsible for the following report, but the preliminary 

 work of sending out the schedules and classifying the records 

 devolved largely on Mr. J. L. Bonhote, the Honorary 

 Secretary ; while the maps have been prepared by Dr. N. ¥, 

 Ticehurst.
